It measures 1\/8 inch (0.1250 inches) in diameter with a 140-degree split point and a multilayer TiAlN coating for extended tool life and heat resistance. The overall length is 2.598 inches (66.00 mm), with a flute length of 1.102 inches (28.00 mm). With a right-hand cutting direction and regular spiral flute geometry, this drill is suited for production environments where consistent hole quality and dimensional accuracy are required. It meets DIN 6537K specification and features coolant-through capability for chip evacuation and thermal control during deep-hole drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in ferrous and non-ferrous machining applications including steel, stainless steel, cast iron, and aluminum. The 5xD flute-to-diameter ratio makes it appropriate for standard jobber-depth holes in CNC machining centers, drill presses, and manual machines where straight-shank tooling is required. The 0.750-inch straight cylindrical shank fits standard drill chucks and collet systems. It is typically installed by machinists and toolroom professionals in manufacturing, fabrication, and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eMultilayer TiAlN coating reduces friction and extends cutting life at elevated temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle improves self-centering and reduces thrust force on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing and heat management during deep drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute geometry compatible with standard CNC and manual setups\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 6537K specification for consistent dimensional and geometric tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style carbide jobber drill for use in steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials as specified by the manufacturer.

Secure the shank fully in the chuck or collet to the manufacturer-recommended engagement depth before starting the spindle. Ensure coolant lines are open and flowing when using the through-coolant feature to prevent chip packing and premature tool failure. Follow applicable shop safety standards and machine guarding requirements during tool changes and drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Multilayer TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.598 inches (66.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.102 inches (28.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches (6 mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.417 inches (36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.906 inches (23.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.020 inches (0.51 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4149129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743693340978,"sku":"4149129","price":133.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d09e56a4569e810def34b8ace2b84455.jpg?v=1788849287","url":"https:\/\/voomisupply.com\/products\/kennametal-4149129-solid-carbide-jobber-drill-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
